摘要
目的：研究沿面放电等离子体－臭氧对空气中微生物的杀灭作用及影响因素。方法：采用人工空气染菌试验法。结果：等离子体－臭氧对空气中的金黄色葡萄球菌作用１ｍｉｎ，杀灭率为９９．９９％，１０ｍｉｎ杀灭率为１００％；对白色念珠菌作用６ｍｉｎ可全部杀灭；对枯草杆菌黑色变种芽孢作用１５ｍｉｎ，杀灭率达到９９．９０％以上，３０ｍｉｍ可全部杀灭。在菌液中加入１０％小牛血清，对消毒效果无明显影响。结论：等离子体－臭氧对空气中的微生物有良好的杀灭作用。
Objective: To investigate the killing effect of plasmasozone (PO) discharging along surface on microorganism in the air and its influence factors. Methods: The testing method of artificial contamination bacteria to air was used in this study. Results: Plasmasozone could kill 99.99% of Staphylococcus aureus in the air within 1 min and 100% within 10 min. It could inactivate all Candida albicans after 6 min. But the sporicidal efficiency of plasmasozone was not so good. Plasmasozone could respectively kill 99. 90% and 100% of spores of Bacillus Sublitis var. Niger in the air within 15 and 30 min action. There was no influence on killing rate when bacterial suspension with 10% calf serum was used. Conclusion: The plasmasozone can effectively activate microorganism in the air, indicating that it will be widely applied in the future.
